Liebherr Skiving³

New Gear Skiving Machine LK 300/500

The principle of gear skiving was invented back over a century ago. Yet in practice the highly dynamic kinematics involved in this method frequently caused major problems: to date this method offered more disadvantages than benefits, as tool wear and tear had a negative impact on machining quality. Liebherr-Verzahntechnik GmbH has now mastered both the mechanics and the technology involved, meaning it is now in a position to create the ideal process for conical and cylindrical tools.

Machine, tool and process from a single source.

ChamferCut

Economical production solution for chamfer/deburring

It is easier said than done – if it takes too much time for two processes to run consecutively on a single machine or single clamping operation, then the design must simply allow both processes to take place simultaneously. As easy as the principle sounds, technical implementation is very complex. We have integrated an entire second processing unit for ChamferCut tools – two machines in one, so to speak. This newly developed solution has eliminated the main disadvantage of previous ChamferCut applications, namely that they prolong machining time.

High chamfer quality and precise chamfer geometry

No bulging or material deformation

Very long service life (including with dry machining)

No needle swarf

ChamferCut is easy to sharpen

Easy tooth-root chamfering

Small diameters possible

Lowest tool costs

Smart Factory: Industry 4.0

Industry 4.0 is a trend that has been prevalent for some time. This transformation via the “smart product” to the “smart factory” is a continuous process. Our customers have very different priorities and requirements, which we need to meet to their complete satisfaction. This is a challenge that we are keen to take on.

Nowadays operators should be able to perform highly complex procedures as simply as possible. To make this happen, they need the appropriate technical support. This support is to be found in modern user interfaces, which also reduce the incidence of problems due to input errors. Thus, for example, our new HMI, LH Geartec, enables hob data to be loaded directly from the manufacturer into the machine. The tools and tool data are then displayed and can immediately be visually checked for completeness and accuracy. The new HMI’s multi-touch function caters for modern forms of machine operation. This graphic input support is also available for operator-created part programs.

REMAN

As good as new

As part of the REMAN program, customers can have a general overhaul performed on their machines, have individual components repaired or decide in favor of a refurbished machine that corresponds to current technical standards.

The complete rebuild which is offered for grinding, hobbing and shaping technologies, involves returning the machines to their original technical state and furnishing them with a new warranty. The REMAN department requires qualified and experienced employees, who have worked on building the machines for many years and, for example, are also familiar with older control systems.
